Paper element: Tap the element several times on a hard surface to remove
excess dirt, or blow compressed air [not exceeding 207 kPa (30 psi)]

Wipe dirt from the inside of the air cleaner housing and cover, using a moist
rag. Be careful to avoid dropping dirt into the air cleaner duct that leads to
the carburetor.
